Title: METHOD AND APPARATUS FOR MEASURING AND PROFILING ABSORBENT MATERIAL IN AN ABSORBENT ARTICLE
Abstract:
Disclosed herein are apparatus, systems and methods of measuring the weight and distribution of the fluff pulp and super absorbent polymer (SAP) or absorbent gelling material (AGM) of absorbent articles. The apparatus may be located at a position after the absorbent cores are formed. Each absorbent article is passed between the light emitter and the camera as well as between the radio transmitter and the radio detector. The camera and radio detector receive the signal transmitted by the light emitter and the radio transmitter respectively through the absorbent articles. The encoder synchronizes the transmission of data by the camera and the radio receiver to the movement of the web. The computer receives the signal data from radio detector and the image data from the camera from each absorbent article and uses the data to determine at least the weight of the fluff pulp and SAP/AGM in the absorbent core.
